This paper identifies two conceptions of security in contemporary concerns over the vulnerability of computers and networks to hostile attack. One is derived from individual-focused conceptions of computer security developed in computer science and engineering. The other is informed by the concerns of national security agencies of government as well as those of corporate intellectual property owners. A comparative evaluation of these two conceptions utilizes the theoretical construct of “securitization,”developed by the Copenhagen School of International Relations.

This article highlights a contemporary privacy problem that falls outside the scope of dominant theoretical approaches. Although these approaches emphasize the connection between privacy and a protected personal (or intimate) sphere, many individuals perceive a threat to privacy in the widespread collection of information even in realms normally considered "public". In identifying and describing the problem of privacy in public, this article is preliminary work in a larger effort to map out future theoretical directions.

This essay warns of eroding accountability in computerized societies. It argues that assumptions about computing and features of situations in which computers are produced create barriers to accountability. Drawing on philosophical analyses of moral blame and responsibility, four barriers are identified: 1) the problem of many hands, 2) the problem of bugs, 3) blaming the computer, and 4) software ownership without liability. The paper concludes with ideas on how to reverse this trend.
